What was the primary purpose of the Naval Combat Demolition Units (NCDUs) during WWII?

The primary purpose of the Naval Combat Demolition Units (NCDUs) during World War II was indeed to clear obstacles for amphibious landings. NCDUs were specially trained teams that played a crucial role in preparing and securing beaches for Allied forces to land safely during operations, such as the D-Day invasion at Normandy. Their tasks included demolishing enemy defenses, such as barbed wire, mines, and other obstacles that could impede the landing troops and equipment. By removing these hazards, they significantly facilitated the success of amphibious assaults, allowing for a smoother entry of ground forces onto hostile shores.

The focus of the NCDUs was not on rescue operations, intelligence gathering, or medical assistance. Although support roles were essential during combat, the NCDUs' specific mission was centered on ensuring that the landing zones were navigable and free of enemy obstructions, making their work pivotal in establishing beachheads during crucial operations in the Pacific and European theaters.
